Keto Ply manufactures IS 710 BWP marine grade plywood at Yamunanagar and supplies it across Mumbai to modular kitchen sink bases, bathroom vanities and sea facing flats from Colaba to Borivali, in 6 mm to 25 mm boards.
IS 710 | BWP Grade | 6 mm to 25 mm
There is one test that separates boiling waterproof plywood from everything else, and it is not subtle: IS 710 requires the board to sit submerged in boiling water for 72 hours and still hold its plies together. BWR grade under IS 303 is boiled in cycles of eight hours; MR grade never goes near boiling water at all. In Mumbai that margin earns its keep faster than anywhere else. Flats are stacked, so a leak from the bathroom above lands in the cabinet below, kitchens are fitted into eight feet of run with the sink base taking daily splash, and salt air reaches interiors from Worli to Bandra all year. Keto Marine Plywood is the BWP grade board in the Keto range, bonded with unextended phenol formaldehyde resin on a high density hardwood core, pressure treated against termite and borer, and pressed under high pressure and temperature.
Boiling water resistance, glue shear and mycological checks are run on production batches against IS 710 before the consignment is dispatched.
Unextended phenol formaldehyde resin with no fillers or extenders, which is the reason the glue line survives 72 hours of boiling rather than minutes.
Consignments to island city, western, central and harbour suburb workshops and sites, slotted around Mumbai's daytime truck restrictions.
Every Keto Ply panel carries the brand's borer, fungus and anti-termite guarantee in writing.
Six things Mumbai architects, kitchen studios and turnkey contractors check before a panel goes into a wet area.
Request a Sample BoardIS 710 submerges the board in boiling water for 72 hours and then tests whether the plies have separated. BWR grade under IS 303 faces three cycles of eight hours; MR grade is never boiled. That gap is the whole point of specifying BWP.
No fillers, no extenders. The resin is what survives the boil, and cheapening it with extenders is the single most common way a board sold as waterproof turns out not to be.
Preservative is pressure impregnated to the retention IS 710 requires, so termite, borer and fungal protection goes through the board rather than sitting on the surface where a saw cut removes it.
IS 710 sets a wet bending strength requirement, not just a dry one, so a shelf in a sink base or a wet area still carries what it is asked to carry after it has been soaked.
Sink bases, bathroom vanities, utility and balcony joinery, and sea facing flats from Colaba to Borivali where salt air never leaves. Everything above the splash zone can stay on MR grade, and we will tell you where that line falls.
Supplied from the Yamunanagar unit with dealer, workshop and project pricing for Mumbai, plus dealership openings across the western and harbour suburbs.
Acceptance values laid down in IS 710 (Marine Plywood - Specification), tested as per IS 1734.
| Test | Method | Requirement | What it means on site |
|---|---|---|---|
| Water Resistance | IS 1734 (Parts 4 & 5) | Submerged in boiling water for 72 hours | Three full days of boiling, against eight hour cycles for BWR grade. |
| Glue Shear Strength (wet) | IS 1734 (Part 4) | 1000 N average, 800 N minimum | The glue line still carries load while the board is soaking wet. |
| Mycological Test | IS 1734 (Part 7) | No appreciable separation at the veneer edges | The bond resists fungal attack in permanently damp locations. |
| Preservative Retention | IS 10013 | Pressure impregnated, minimum 12 kg/m³ for CCA, CCB or ACC | Protection goes through the board, so a saw cut does not expose untreated wood. |
| Wet Bending Strength | IS 1734 (Part 11) | MOR 25 N/mm² along and 15 N/mm² across, tested wet | A shelf in a sink base still carries load after it has been soaked. |
| Moisture Content | IS 1734 (Part 1) | Not less than 5% and not more than 15% | A seasoned board that will not swell and push shutters out of line. |
